We've got a beast of a laptop to give away for free as part of our Reg Hardware competition.
If you're looking for something that packs a punch and half, this should be just the fillip. It's the afore mentioned Samsung RF711 17.3in Core i7 which should be more than enough wallop for most of your needs.
It'll take …

D'uh

Beast, really?

It's got a 2 GHz current gen i-7, so nothing special there, 6 GiB of DDR3 is admittedly a lot of RAM (though probably not that useful, in truth) and 900 pixels for the height is indeed FAIL on the screen (that's why people keep saying so) of a "17 inch" format laptop. Even the graphics is pretty mediocre, really, for the term 'beast'. Not to be a git about this but I'm typing from an M18X with 2x HD 6990M in Crossfire and a considerably faster i-7 and I'm still not close to the 'maxed' builds possible for the line. These machines and their competitors are "Beasts of a laptop" not this nice executive toy.
